Grrrrr. I was just about finished typing this in & I accidently hit the clear button on the keyboard. Poof gone....
ANYWHO, I have a retired master mech friend who agrees with the gunk / water in the tank theory. I threw a can of Heat in the last tank to see if that helps, Any other suggestions on Brand? I toyed with pulling the tank & flushing it out till I read manual & figgered it was kinduva job...
No on the vapor lock. Not when I refill the tank anyway. Old pump is gone, But It may be worth a trip to pull n save again to try & rule it out.
Could the fuel pressure reg. be causing this???
